Answer:
y = (1/2)x - 4
Step-by-step explanation:
y = mx + b
y = (1/2)x + b
-3 = (1/2)(2) + b
-3 = 1 + b
b = -4
y = (1/2)x - 4
The probability that a randomly selected person at a show has seen the band play live before is 30%. A "superfan" is defined as someone who has seen the band play live at least 10 times. The probability that a person at a show is a "superfan" is 20%. Two people are selected at random. What is the probability that both people have both seen the band perform live before, and are superfans?
Answer:
0.09 and 0.04
Step-by-step explanation:
The probability that a randomly-selected person at a show has seen the band play live before is 30%=0.30
The probability that a person at a show is a "superfan" is 20%=0.20
Two people are selected at random.
The probability that both people have both seen the band perform live before = The probability that the first person has seen the band live before and the second person also has seen the band live before.
=0.30 x 0.30
=0.09
Similarly, the probability that both are "superfans" = The probability that the first person is a superfan and the probability that the second person is a superfan.
=0.20 x 0.20
=0.04
Hence, the probability that both people have both seen the band perform live before, and are "superfans" are 0.09 and 0.04 respectively.

how do you solve this equation?
x/2 - x = x/4 + 6
Answer:
[tex]x=-8[/tex]
Step-by-step explanation:
[tex]\frac{x}2} -x=\frac{x}{4} +6[/tex]
Let's begin by getting rid of the fractions by multiplying both sides of the equation by the least common multiple of the denominators 2 & 4 (4).
[tex]4(\frac{x}2} -x)=4(\frac{x}{4} +6)[/tex]
Distribute:
[tex]\frac{4x}{2} -4x=\frac{4x}{4} +24[/tex]
Simplify:
[tex]2x-4x=x+24[/tex]
Combine like terms:
[tex]-2x=x+24[/tex]
Subtract [tex]x[/tex] from both sides of the equation:
[tex]-3x=24[/tex]
Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]-3[/tex]:
[tex]x=-\frac{24}{3}[/tex]
Simplify:
[tex]x=-8[/tex]

9. ∠DEF and ∠FEG are complementary. m∠DEF = (3x − 4)°, and m∠FEG = (5x + 6)°.
Find the measures of both angles.
Answer:
29°61°Step-by-step explanation:
Complementary angles are two angles that add up to be 90 degrees.
We can write an equation and solve for x.
(3x - 4) + (5x + 6) = 90
~Combine like terms
8x + 2 = 90
~Subtract 2 to both sides
8x = 88
~Divide 8 to both sides
x = 11
Angle DEF:
3x − 4
3(11) - 4
33 - 4
29°
Angle FEG:
5x + 6
5(11) + 6
55 + 6
61°
Check:
29 + 61 = 90°

Molly has $45 in her wallet, which is 3 times as much money as her brother has.
Write an equation to represent this situation, where a represents the amount of money Molly’s brother has.
45 =
Answer: 45 divided by 3 equals 15
he has 15 dollars
Step-by-step explanation: 45= 3 times 15
Answer: 45=3a a=15
Step-by-step explanation:
We know that Molly has $45 or 3 times the amount of money her brother has, and a represents the amount of money her brother has. So we would multiply a by 3. In order to find a we just divide 45 by 3.

The required rate for granola in dollars per pound is 1.25.
What is Unitary method ?In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.
Given that,
The total money spent on granola is $3.75.
And, the amount of granola is 3 pounds.
The unit rate for the given case can be found using unitary method as,
Money spent for 3 pounds = $3.75
Then, money spent for 1 pound = 3.75/3 = $1.25
Hence, the rate of granola $1.25 per pound.

A ticket to a baseball game costs $32. Each soda at the game costs $4. Shawn may spend no more than $50. He buys 1 ticket and x sodas. (ignore what I wrote already i think it’s wrong)
Answer:
32 + 4x ≤ 50
Step-by-step explanation:
Cost of tickets = $32
Cost of soda = $4
Total spent = $50
When we say "no more than", we mean less than or equal to (≤)
He buys 1 tickets and x sodas
32 + 4x ≤ 50
4x ≤ 50 - 32
4x ≤ 18
Divide both sides by 4
x ≤ 18 / 4
x ≤ 4.5
Shawn can buy more than 4 sodas

Which sequence of steps is a correct derivation of the difference quotient for f(x) = 3 – log x?
Answer:
Step-by-step explanation:
Where are the answer choices?
Still, it's possible to help you without your having shared those choices.
The "difference quotient" is defined as:
f(x + h) - f(x)
--------------------
h
where h represents an incremental (small) change in x.
Here f(x) = 3 - log x, and so f(x + h) = 3 - log (x + h).
Therefore the difference quotient is:
{3 - log (x + h)} - {3 - log x}
-------------------------------------
h
This can be simplified. In the numerator we have 3 - 3, so the numerator simplifies to -log (x + h) + log x
and the difference quotient is
-log ( x + h) + log x
---------------------------
h
This can be rewritten as
log x - log (x + h) x x
--------------------------- , or (1/h)*log ------------ , or (1/h) log { ----------- }
h (x + h) x + h
